if you converted from an M6 car you have to use a different correction in LS1edit, if you search here you can find the info - I posted it a while back but I forget. If I remember I had to divide the tire diameter by 2.35 to make it work right, I had 11.27 for tire diameter for 26.5" tires.

If you converted from an A4 car it should be right..
